Perdix is for Partridge

Depending on the version of the myth that you read, Perdix is either the name of Daedalus's sister or of her son, the prodigy who Daedalus killed out of jealousy. The genus name for partridges is, indeed, perdix ; gray partridges are perdix perdix.

It's said that a partridge (the spirit of the nephew or sister, depending on who you're reading) haunted Daedalus when he buried Icarus. In our production, a black partridge-like bird appears at every death.

Here's a YouTube clip of a gray partridge (not a nail-biter, but it gives you some sense of how they move):

And here's another short clip, where you can hear the calls they make:

And one more: apparently partridge fighting is quite popular in South Asia. Not endorsing animal fighting, but it gives a different perspective on their movement patterns):

Finally, one more (audio) clip of a partridge call and flight alarm:
